1 A. Introduction 1. Title: System Restoration from Blackstart Resources 2. Number: EOP Purpose: Ensure plans, Facilities, and personnel are prepared to enable System restoration from Blackstart Resources to assure reliability is maintained during restoration and priority is placed on restoring the Interconnection. 4. Applicability: 4.1. Transmission Operators Generator Operators Transmission Owners identified in the Transmission Operators restoration plan Distribution Providers identified in the Transmission Operators restoration plan. 5. Proposed Effective Date: Twenty-four months after the first day of the first calendar quarter following applicable regulatory approval. In those jurisdictions where no regulatory approval is required, all requirements go into effect twenty-four months after Board of Trustees adoption. B. Requirements R1. Each Transmission Operator shall have a restoration plan approved by its Reliability Coordinator. The restoration plan shall allow for restoring the Transmission Operator s System following a Disturbance in which one or more areas of the Bulk Electric System (BES) shuts down and the use of Blackstart Resources is required to restore the shut down area to service, to a state whereby the choice of the next Load to be restored is not driven by the need to control frequency or voltage regardless of whether the Blackstart Resource is located within the Transmission Operator s System. The restoration plan shall include: [Violation Risk Factor = High] [Time Horizon = Operations Planning] R1.1. Strategies for system restoration that are coordinated with the Reliability Coordinator s high level strategy for restoring the Interconnection. R1.2. A description of how all Agreements or mutually agreed upon procedures or protocols for off-site power requirements of nuclear power plants, including priority of restoration, will be fulfilled during System restoration. R1.3. Procedures for restoring interconnections with other Transmission Operators under the direction of the Reliability Coordinator. R1.4. Identification of each Blackstart Resource and its characteristics including but not limited to the following: the name of the Blackstart Resource, location, megawatt and megavar capacity, and type of unit. R1.5. Identification of Cranking Paths and initial switching requirements between each Blackstart Resource and the unit(s) to be started. R1.6. Identification of acceptable operating voltage and frequency limits during restoration. Adopted by NERC Board of Trustees: August 5,
